@Override
public void flip(final LWComponentPeer<?, ?> peer, final Image backBuffer,
final int x1, final int y1, final int x2, final int y2,

g.drawImage(backBuffer, x1, y1, x2, y2, x1, y1, x2, y2, null);
} finally {
g.dispose();
}

try {
bg.setBackground(peer.getBackground());

示例2: CDropTarget
import sun.lwawt.LWComponentPeer; //导入依赖的package包/类
private CDropTarget(DropTarget dropTarget, Component component, ComponentPeer peer) {

// Create native dragging destination:
fNativeDropTarget = this.createNativeDropTarget(dropTarget, component, peer, nativePeer);
if (fNativeDropTarget == 0) {

@Override
public Image createBackBuffer(final LWComponentPeer<?, ?> peer) {
final Rectangle r = peer.getBounds();
// It is possible for the component to have size 0x0, adjust it to
// be at least 1x1 to avoid IAE

final int transparency = peer.isTranslucent() ? Transparency.TRANSLUCENT
: Transparency.OPAQUE;
